I really like this movie, and would have like it even better watched filtered. For reasons outside of our control we were unable to acquire the needed filter. There was a single scene that occurs within the first 15 minutes of the movie that was not necessary (an intelligent director can tell the audience the same thing without showing so much). Otherwise there wasn't much to be filtered other than comic book action sequences, which might be a little too much for some.
There was an overall good message. Tony Stark realized something he was doing wrong and then did all in his power to try to makeup for his misdeeds. He put aside all his temporal desires to help aid a greater cause. He was able to play this role realistically too. He wasn't void of all vices like Superman; but being completely human, I think made his character more relateable (though his wealth, like that of Bruce Wayne, could be construed as their super hero power). It's a standard comic bok superhero story, nothing too new there.
